CIUDAD JUAREZ, Mexico -- Authorities say masked gunmen burst into a bar in the northern city of Chihuahua and opened fire, killing 14 people.
Chihuahua state prosecutors' spokesman Carlos Gonzalez says at least seven assailants in police-like uniforms arrived at the bar called El Colorado in several cars late Friday, barged into the building and opened fire.
Gonzalez says two people were wounded. He says investigators are still trying to determine who was behind the attack.
Chihuahua state is across the border from Texas and has seen a spike in violence since 2008, when the Sinaloa and Juarez drug cartels began fighting for control of lucrative smuggling routes.
